Free online tools built for developers, creators, and everyday users.
FJ Techtools is a free collection of browser-based utilities started in 2020. The goal is simple: provide fast, clean, and reliable tools with no signup walls, no watermarks, and no paywalls. Every tool runs entirely in your browser — nothing you paste or upload ever leaves your machine.
What started as a handful of barcode and data tools has grown into a toolkit covering barcode generation and validation, image compression and resizing, QR code creation, data format conversion, color utilities, and more — with new tools added regularly.
FJ Techtools is built and maintained by Faraz Javed, a Senior Full Stack Developer with 9+ years of experience building web applications.
